This is what I've been doing on and off since December. The top of the image is really just to show the make up, structure or architecture. 12 of them were on each board, 2 rows of 6. The money is in the contacts in the green glass tubes. 10 tubes per unit, 2 contacts per tube.
You can see some of the removed tubes, below them are some of the contacts with the glass off and to the right of them the contacts with the gold and platinum off.
The contacts are Nickle and highly magnetic, so we simply crush them and recover the contacts from the glass with a magnet. Nice clean separation. I soak them in 70% HNO3 for 24 hours then remove them with a magnet and drop them into my 2 liter beaker.
Here comes the fun, a gentle mist of H2o with a good stir and in about 5 minutes the gold and platinum is off in foil form but still mixed in with the contacts. Using the magnet I lift some of them out, drop them in H2o to free up the foils, then remove the contacts from the H2o with the magnet. You can guess the rest.
Platinum on the spoon is damp foil, Au in the beaker, 31.2 grams.
